Deriving Generic Transformation Matrices for Multi-Axis Milling Machine

نویسنده

  • Alan C. Lin
چکیده

This paper proposes a new method to find the equations of transformation matrix for the rotation angles of the two rotational axes and the coordinates of the three linear axes of an orthogonal multi-axis milling machine. This approach provides intuitive physical meanings for rotation angles of multi-axis machines, which can be used to evaluate the accuracy of the conversion from CL data to NC data. Keywords—CAM, multi-axis milling machining.

Three New Systematic Approaches for Computing Heffron-Phillips Multi-Machine Model Coefficients (RESEARCH NOTE)

This paper presents three new systematic approaches for computing coefficient matrices of the Heffron-Phillips multi-machine model (K1, …, K6). The amount of computations needed for conventional and three new approaches are compared by counting number of multiplications and divisions. The advantages of new approaches are: (1) their computation burdens are less than 73 percent of that of convent...

Generating Multiaxis Tool Paths for Die and Mold Making with Evolutionary Algorithms

Defining tool paths for multiaxis milling is a difficult task that requires knowledge about the process and the behavior of the machine tool. Because of the high risks of multiaxis movements within a real machine, the resulting paths are safe but normally sub-optimal. This article introduces a new method to obtain tool paths, which are free of collisions and optimal in consideration, the machin...

A Common Weight Multi-criteria Decision analysis-data Envelopment Analysis Approach with Assurance Region for Weight Derivation from Pairwise Comparison Matrices

Deriving weights from a pairwise comparison matrix (PCM) is a subject for which a wide range of methods have ever been presented. This paper proposes a common weight multi criteria decision analysis-data envelopment analysis (MCDA-DEA) approach with assurance region for weight derivation from a PCM. The proposed model has several merits over the competing approaches and removes the drawbacks of...
